Phys.org / String theory is uniquely derived from basic assumptions about the universe, physicists show
If you could take an apple and break it into smaller and smaller parts, you would find molecules, then atoms, followed by subatomic particles like protons and the quarks and gluons that make them up. You might think you hit ...
Phys.org / Q&A: Is it time to expand our thinking about dark matter? A new study says yes
We may be more in the dark about dark matter than previously thought, according to a new analysis of distant galaxy clusters. Yale astrophysicist Priyamvada Natarajan, a leading theorist on the nature of black holes and dark ...
Phys.org / Webb discovers one of the universe's first galaxies
Scientists have discovered a galaxy as it was 13 billion years ago, 800 million years after the Big Bang. It contains possible evidence of the universe's first stars and is one of the most chemically primitive galaxies observed ...
Phys.org / New book examines national pension crisis
Public pension debt has far-reaching consequences, yet there appear to be limited options for addressing it. State and local governments often turn to legislation to reduce plan benefits. These reforms have been challenged ...
Tech Xplore / Scientists develop near-invisible solar cells that could turn windows into power generators
Imagine a car whose windows and sunroof can help top up its battery while parked under the sun, or a pair of smart glasses whose lenses can harvest light to power built-in electronics.
Phys.org / Coal pollution is cutting solar power output worldwide, study finds
New research led by the University of Oxford and University College London (UCL) has revealed that pollution from coal-fired power plants is significantly reducing the energy output of solar photovoltaic (solar PV) installations, ...
Phys.org / If AI can translate instantly, why learn another language?
From live speech translation in video calls to auto-dubbing on TikTok, the technology to dissolve language barriers has arrived. Real-time translation powered by artificial intelligence (AI) is now embedded in everyday life.
Phys.org / In quantum gravity, the cosmological constant may behave similar to the quantum Hall effect
Trying to solve quantum gravity is frustrating. We have made tremendous progress in quantum theory, but it seems that every time we find a new quantum technique, there's a reason it doesn't quite work with gravity. Take, ...
Phys.org / People overestimate how confident AI systems are in their responses, experiments reveal
Artificial intelligence (AI) systems, particularly conversational agents such as ChatGPT or Gemini, are now used daily by a growing number of people worldwide. While many users trust the answers of AI agents to their queries, ...
Phys.org / eROSITA discovers a 'changing-look' Seyfert galaxy
Astronomers have tracked a dramatic "changing-look" active galactic nucleus (AGN) whose central supermassive black hole appeared to switch off and then rapidly reignite. The galaxy, HE 1237−2252, dimmed in X-rays by a factor ...
Phys.org / Mathematical analysis reveals a hidden 'golden rule' in abstract art
A mathematical method borrowed from topology can reveal structural properties of visual art that correspond to how people perceive and respond to them, according to a new study published in PLOS Computational Biology by Jacek ...
Phys.org / Gravitational waves from colliding black holes may allow detection of dark matter
Dark matter is thought to make up most of the matter in the universe, but the only way it interacts with its surroundings is through gravity. If two colliding black holes spiral through a dense region of dark matter and merge, ...
